1.75″ Golf Ball Hail Confirmed — Mayville, Dodge County WI (11:32 PM CDT Sept 3)

A severe thunderstorm moved through Dodge County, Wisconsin in the late hours of Wednesday, September 3, 2026, producing confirmed golf ball-sized hail in and around Mayville. The storm struck just before midnight local time, leaving homeowners in Mayville, Waupun, Beaver Dam, Horicon, Hartford, and Juneau with a morning of questions about what the night left behind on their roofs, siding, and property.

This event was entirely separate from an earlier severe thunderstorm system that had already affected Waukesha, Milwaukee, and Washington counties earlier that same day. The Dodge County storm moved through overnight — the kind of event where most residents are asleep and the damage doesn’t reveal itself until daylight. If you live or own property in the affected area, here’s what was officially confirmed and what to do next.

What the National Weather Service Confirmed

The National Weather Service office in Milwaukee/Sullivan (NWS MKX) recorded two hail reports in the Mayville area on the night of September 3, 2026, as logged in Storm Prediction Center (SPC) storm reports:

• 11:32 PM CDT — Mayville, Dodge County, WI: Hail measuring 1.75 inches in diameter — roughly the size of a golf ball. This is the larger of the two confirmed reports and represents a significant hail event capable of causing real damage to roofing materials, siding, gutters, and vehicles.
• 11:28 PM CDT — 1 West of Mayville, Dodge County, WI: Hail measuring 1.00 inch in diameter — dime to quarter-sized. Even at this threshold, hail can crack or dent softer roofing materials and leave impact marks on aluminum and vinyl siding.

Dodge County sits approximately 119 miles north-northwest of Oak Brook, Illinois, placing it squarely within Allied Emergency Services’ southern Wisconsin service area. NWS Milwaukee/Sullivan is the authoritative source for these reports; you can review current and archived severe weather data directly at weather.gov.

It’s worth noting what NWS storm reports document: they capture hail size and location as reported by trained spotters or observed at the time the storm passes. What they don’t capture is the cumulative property damage across the affected area — that gets discovered on rooftops, along gutters, and against siding in the days that follow.

What Homeowners in Mayville, Waupun, Beaver Dam, Horicon, Hartford, and Juneau Should Check Now

Golf ball-sized hail at 1.75 inches is large enough to cause functional damage — not just cosmetic marks. If your property is in or near any of the affected towns, a careful post-storm inspection is worth doing before you file anything or make any calls. Here’s where to look:

Roof

• Asphalt shingles: Look for dark circular impact marks, dimpling, or spots where granules have been knocked loose. Granule loss accelerates weathering and shortens shingle life significantly — even when the shingles look intact from the ground.
• Metal components: Check ridge caps, flashing, vent covers, and any exposed metal trim. These surfaces show hail impacts as small dents or dings and are among the most reliable physical indicators of a significant event.
• Gutters and downspouts: Hail dents gutters and downspout caps. Check the downspout splash blocks for accumulated granules — granule washout is a strong signal of shingle damage above.
• Skylights and chimney caps: Cracking or pitting in polycarbonate skylight panels is common after golf ball-sized hail.

Siding

• Vinyl siding: Look for cracks, fractures along panel edges, and impact dents — particularly on south- and west-facing walls, which typically take the hardest hits from hail driven by the storm’s track.
• Aluminum siding: Check for dimpling and denting. Even cosmetic damage can compromise a panel’s long-term weather resistance if left unaddressed.
• Trim and fascia boards: Wood trim can show splits or impact marks that are easy to miss from the ground.

Windows and Screens

• Look for cracked glass, broken or bent window screens, and damaged window well covers. Screen damage is often the first visible sign of a significant hail event and a useful indicator of how much force the storm delivered.

Trees, Landscaping, and Outdoor Property

• Stripped leaves, broken branches, and dented garden equipment can all serve as on-the-ground indicators of hail size and coverage. If your yard shows obvious storm damage, treat the roof as suspect until inspected.

Interior — Signs of Water Intrusion

• After a hail event, walk through your attic or crawl space within the next 24 to 48 hours. Look for wet insulation, daylight visible through roof decking, or fresh water stains on interior ceilings. A compromised roof doesn’t always leak immediately — but it will under the next significant rain.

Do not attempt to climb onto your roof in the aftermath of a storm, especially overnight or on wet surfaces. A thorough ground-level visual inspection and a careful attic walkthrough give you enough information to take the right next step safely.

If You Find Damage

Discovering storm damage on your property doesn’t have to be overwhelming. Taking the right steps now protects both your home and your insurance claim.

Document Before Anything Else

Before any repairs begin, photograph everything — from multiple angles, in good daylight. Take wide establishing shots of the full roof face and each side of the house, then close-ups that clearly show individual impact marks or cracked materials. Note the date and time your photos were taken. This documentation becomes part of your claim record and gives your insurer’s adjuster the clearest possible picture of what the storm left behind.

Contact Your Insurance Company

Report the damage to your homeowner’s insurance carrier and open a claim. Ask about their timeline for dispatching an adjuster. Most carriers actively track NWS storm reports, and a confirmed hail event like this one in Dodge County on September 3 makes the initial claim conversation straightforward.

Work With a Licensed Restoration Contractor

A licensed restoration contractor can provide a detailed, written damage assessment and repair estimate, and can meet with your insurance adjuster on-site to ensure all legitimate damage is properly documented and included in the scope of work. Allied Emergency Services is a licensed roofing and restoration contractor — we do not act as a public adjuster and do not negotiate, settle, or adjust insurance claims on behalf of homeowners. What we do is make sure the full scope of storm damage is identified, documented accurately, and repaired correctly.

Don’t Wait Too Long

Most homeowner policies include filing deadlines for storm damage — typically one to three years, though some carriers have tightened those windows in recent years. More practically, a roof compromised by golf ball-sized hail is one heavy rain away from interior water damage. Acting within the first few weeks keeps a manageable repair from becoming a significantly larger and more expensive problem.
